After being planted in the greenhouse for a period of time, sometimes the soil will grow moss or even turn red. If it goes on for a long time, it will seriously affect the yield and quality of planted crops, and even affect the normal growth of crops. When we encounter this situation, how should we deal with it?
Precaution:
1. Prohibit chemical fertilizers and increase the application of organic biological fertilizers, especially straw organic fertilizers. It can not only reduce the appearance of harmful cations, but also consume the nitrogen in the topsoil during the decomposition process, reduce the excessive accumulation of nitrate nitrogen, and increase the buffering effect of the soil.
2. Change the stubble gap, remove the shed film, and use the rain in the rainy season to let the natural rain water wash the salt.
3. The drip irrigation technology can keep the soil loose, slow down the accumulation of salt in the soil, and slow down the process of soil salinization.
